WhatsApp Messaging Limits

Overview

This guide explains how WhatsApp messaging limits work, what they apply to, and how your sending capacity increases over time.

Messaging limits control how many new conversations your business can start using message templates.

What Are Messaging Limits?

Messaging limits define how many unique customers you can message within a 24-hour period using template messages.

• Limits apply only to business-initiated messages (templates)
• They do not apply to replies within the 24-hour customer service window

Important Concept

There are two types of messaging on WhatsApp:

1. Customer-initiated conversations

• The customer messages you first
• You can reply freely for 24 hours
• No limits apply

2. Business-initiated conversations

• You message the customer first
• You must use a template message
• Messaging limits apply

Messaging Limit Tiers

WhatsApp uses a tier-based system:

How Limits Work

• Limits are calculated over a 24-hour rolling window
• Only new conversations are counted
• Messages within an active 24-hour conversation do not count

What does “24-hour rolling window” mean?

The limit does not reset at a fixed time (such as midnight). Instead, each conversation is counted for 24 hours from the time it was sent.

Example:

• If you send a message to a customer at 10:00 AM
  → that conversation will count toward your limit until 10:00 AM the next day
• After 24 hours
  → the conversation is no longer counted, and you can start a new one instead

Portfolio-Level Limits

Messaging limits are applied at the business portfolio level, not per phone number.

• All phone numbers share the same limit
• The highest limit among your numbers is applied to the entire portfolio

Example:

• One number has 100K limit
• Others have lower limits

→ Your portfolio limit becomes 100K, shared across all numbers

This means one phone number can use the entire daily limit.

How to Increase Your Limit

WhatsApp automatically increases your messaging limit based on your activity and quality.

To qualify for an upgrade:

• Maintain Medium or High quality rating
• Use at least 50% of your current limit within 7 days

If both conditions are met:

• Your limit is automatically upgraded (usually within a few hours)

Scaling from 250 to 2K

New businesses start with a 250 daily limit.

To unlock the next level (2K), you must complete one of the following:

• Verify your business in Meta Business Manager
• Get verified by your solution provider
• Send 2,000 template messages to unique users within 30 days using high-quality templates

Alternate Path Program

If your business is not verified, you can still increase your limit through activity.

Requirements:

• Send at least 1,000 business-initiated conversations within 30 days
• Maintain high message quality

Meta will review your account and decide whether to increase your limit.

Quality Rating

Your messaging quality directly affects your ability to scale.

Quality levels:

• High — Good performance
• Medium — Acceptable
• Low — Risk of restrictions

When Limits May Not Increase

Your limit may not increase if:

• Message quality is low
• Users block or report your messages
• You are not using enough of your current limit

Best Practices

• Send messages only to users who opted in

• Keep your messages relevant and clear

• Avoid sending large volumes suddenly

• Monitor your quality rating regularly

Key Takeaway

Messaging limits are based on how many people you reach, not how many messages you send.

Your limit increases as you:

• Send messages consistently
• Maintain good quality
• Build positive engagement

FAQ

Do messaging limits apply to replies?

No. They only apply to template messages sent outside the 24-hour window.

Do multiple messages count separately?

No. Messages to the same user count as one conversation.

How often do limits reset?

Every 24 hours (rolling window).

Can I manually increase my limit?

No. Limits are updated automatically by WhatsApp.

What happens if I reach my limit?

You won’t be able to start new conversations until the limit resets.

Why didn’t my limit increase?

This may happen if:

• You didn’t reach 50% of your limit
• Your quality rating is not sufficient
• Meta has not completed the review yet
